# DAC8830IDR

**Texas Instruments** · Digital To Analog Converters (DAC) · SO-8

DAC8830IDR from Texas Instruments, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | output | Analog output of the 16-bit DAC providing unipolar voltage swing from 0 V to +VREF with unbuffered operation. |
| 2 | AGND | power_in | Analog ground reference for the DAC output stage. |
| 3 | VREF | power_in | Voltage reference input with range 1.25 V to VDD that determines full-scale output voltage. |
| 4 | CS | input | Chip select input (active low); serial data clocking into the register occurs only when CS is held low. |
| 5 | SCLK | input | Serial clock input supporting frequencies up to 50 MHz for serial data synchronization and transfer. |
| 6 | SDI | input | Serial data input accepting 16-bit MSB-first words, latched on the rising edge of SCLK. |
| 7 | DGND | power_in | Digital ground for the serial interface and control logic. |
| 8 | VDD | power_in | Analog power supply input with range 2.7 V to 5.5 V and typical supply current 5 to 20 μA. |
